Karr, 41, goes on trial this week before Chouteau on five misdemeanor counts of possessing child pornography.

Wong ruled that prosecutors' misleading statements and their loss of a computer -- which was seized from Karr in 2001 and allegedly contained five sexually explicit photographs of children -- did not justify opening the documents to the public. A copy of the information on Karr's computer has been recovered.

The former schoolteacher vanished after he was charged five years ago. He was arrested last month in Thailand after confessing to killing 6-year-old JonBenet Ramsey in Boulder, Colo., in 1996. Karr was extradited to Santa Rosa after prosecutors in Boulder decided his confession was bogus.
